Product Description:

The KSM02.1B-061C-61N-M1-HG0-ET-L3-D7-NN-FW is a motor-integrated servo drive produced by Bosch Rexroth Indramat for the KSM Motor Integrated Servo Drives series. This unit is series level 2 and design version 1 with the standard mechanical option. By combining drive electronics, a synchronous motor, and feedback elements in one housing, the unit simplifies decentralized machine layouts and reduces cabinet wiring. Its task in industrial automation is to deliver precise torque and speed control directly on the axis so conveyors, pick-and-place modules, or tooling slides can be positioned with short cycle times and minimal electrical complexity.

Power is supplied through a common DC link at DC 750 V, giving the drive headroom for dynamic acceleration while keeping wiring current moderate. Heat produced by the embedded inverter is removed by natural convection, so no fans are required and maintenance is reduced. Position feedback is generated by an optical encoder that provides 128 signal periods per mechanical turn and communicates via the Hiperface interface. This resolution supports fine interpolation inside the drive controller, and the multi-turn absolute encoder reports axis position immediately after power-up without a homing move.

Functional safety is addressed with Safe Torque Off (STO), allowing immediate energy isolation without mechanical relays. Power, Ethernet, and brake lines enter through the Hybrid Connector, and motion commands travel over the Multi-Ethernet network for integration with compatible control architectures. The drive uses winding code 61 and motor length C in the compact 061 frame. A plain shaft with a shaft seal transmits torque while helping block lubricants. The unit has a basic performance rating and is intended for decentralized servo axes that require integrated safety and direct motor-mounted drive control.
